KG-1 Heat Absorbing Filter

Description

Heat absorbing glass is used to reduce the amount of heat transmitted through an optical system. The KG filter glasses effectively absorb wavelengths beyond the visible spectrum. Unlike hot mirrors, which reflect the infrared wavelengths, KG filter glasses absorb the infrared radiation and then dissipate the heat into the air around the glass. KG filter glasses can also be utilized as a shortpass filter, in order to pass the visible and block the IR.
The Filter is 42mm in diameter. Thanks for looking!
